What is Metabolic Age Calculator?

▾

Metabolic age compares your BMR to the average for your chronological age. A lower metabolic age (higher BMR than peers) reflects better muscle mass and metabolic health.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

Vzorec

How to Metabolic Age Calculator

▾

1BMR = 88.4 + 13.4*weight + 4.8*height - 5.68*age (Mifflin-St Jeor, male)
2Metabolic age = Chronological age x (Average BMR for age / Your BMR)
3Higher muscle mass leads to higher BMR and younger metabolic age

Worked Examples

▾

Example 1

Given:Age 35, BMR 1,900 kcal - average is 1,800 for 35-year-olds

Výsledok:Metabolic age approx 33 - two years younger metabolically
